集群配置
安装rabbitmq 三台机子都配置对应得hosts文件 [rootlocalhost ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.128 rabbitmq-1
192.168.10.129 rabbitmq-2
192.168.10.130 rabbitmq-3三台机子都得安排rabbitmq 目前三台机子都上传了对应得安装包 [rootlocalhost ~]# ls
anaconda-ks.cfg rabbitmq-server-3.7.10-1.el7.noarch.rpm erlang-21.3.8.21-1.el7.x86_64.rpm
[rootlocalhost ~]# yum install -y erlang-21.3.8.21-1.el7.x86_64.rpm
[rootlocalhost ~]# yum install -y rabbitmq-server-3.7.10-1.el7.noarch.rpm启动rabbitmq
[rootlocalhost ~]# systemctl daemon-reload
[rootlocalhost ~]# systemctl start rabbitmq-server开启远程登录
[rootlocalhost ~]# cd /usr/share/doc/rabbitmq-server-3.7.10/
[rootlocalhost rabbitmq-server-3.7.10]# cp rabbitmq.config.example /etc/rabbitmq
[rootlocalhost rabbitmq-server-3.7.10]# cd /etc/rabbitmq/
[rootlocalhost rabbitmq]# ls
enabled_plugins rabbitmq.config.example
[rootlocalhost rabbitmq]# mv rabbitmq.config.example rabbitmq.config
[rootlocalhost rabbitmq]# vim rabbitmq.config 修改下面配置文件的内容 第349行 # 开启rabbitmq的web访问界面
[rootlocalhost ~]# rabbitmq-plugins enable rabbitmq_management输入对应的ip即可以登录 有默认用户guest 密码也是guest 添加用户并且授权用户
[rootlocalhost ~]# rabbitmqctl add_user root 1
Adding user root ...
[rootlocalhost ~]# rabbitmqctl set_user_tags root administrator
Setting tags for user root to [administrator] ...
[rootlocalhost ~]# rabbitmqctl list_users
Listing users ...
user tags
guest [administrator]
root [administrator]
[rootlocalhost ~]# rabbitmqctl set_permissions -p / root .* .* .*
Setting permissions for user root in vhost / ...添加数据存放目录和日志存放目录
[rootlocalhost ~]# mkdir -p /data/rabbitmq/data
[rootlocalhost ~]# mkdir -p /data/rabbitmq/logs
[rootlocalhost ~]# chmod 777 -R /data/rabbitmq
[rootlocalhost ~]# chown rabbitmq.rabbitmq /data/ -R
创建配置文件:
[rootlocalhost ~]# vim /etc/rabbitmq/rabbitmq-env.conf
[rootlocalhost ~]# cat /etc/rabbitmq/rabbitmq-env.conf
RABBITMQ_MNESIA_BASE/data/rabbitmq/data
RABBITMQ_LOG_BASE/data/rabbitmq/logs
重启服务
[rootlocalhost ~]# systemctl restart rabbitmq-server查看端口
[rootlocalhost ~]# ss -ntlp4369 – erlang发现端口 5672 --程序连接端口 15672 – 管理界面ui端口 25672 – server间内部通信口 拷⻉erlang.cookie
[rootlocalhost ~]# cd /var/lib/rabbitmq/
# ⽤scp的⽅式将rabbitmq-1节点的.erlang.cookie的值复制到其他两个节点中。
[rootlocalhost rabbitmq]# scp .erlang.cookie 192.168.10.129:/var/lib/rabbitmq/
root192.168.10.129s password:
.erlang.cookie 100% 20 14.6KB/s 00:00
[rootlocalhost rabbitmq]# scp .erlang.cookie 192.168.10.130:/var/lib/rabbitmq/
root192.168.10.130s password:
.erlang.cookie各节点是经由过程⼀个magic cookie来实现的,这个cookie存放在/var/lib/rabbitmq/.erlang.cookie中⽂件是400的权限。所以必须保证各节点cookie⼀致,不然节点之间就⽆法通信.
(官方在介绍集群的文档中提到过.erlang.cookie 一般会存在这两个地址第一个是home/.erlang.cookie第二个地方就是/var/lib/rabbitmq/.erlang.cookie。如果我们使用解压缩方式安装部署的rabbitmq那么这个文件会在{home}目录下也就是$home/.erlang.cookie。如果我们使用rpm等安装包方式进行安装的那么这个文件会在/var/lib/rabbitmq目录下。)
将mq-2、mq-3作为内存节点加⼊mq-1节点集群中
在mq-2、mq-3执⾏如下命令
[rootlocalhost ~]# systemctl restart rabbitmq-server
[rootlocalhost ~]# rabbitmqctl stop_app #停止节点
[rootlocalhost ~]# rabbitmqctl reset #如果有数据需要重置没有则不用
[rootlocalhost ~]# rabbitmqctl join_cluster --ram rabbitrabbitmq-1 #添加到磁盘节点
Clustering node rabbitrabbitmq-2 with rabbitrabbitmq-1 ...
[rootlocalhost ~]# rabbitmqctl start_app #启动节点
Starting node rabbitrabbitmq-2 ...[rootlocalhost ~]# systemctl restart rabbitmq-server
[rootlocalhost ~]# rabbitmqctl stop_app
[rootlocalhost ~]# rabbitmqctl reset
[rootlocalhost ~]# rabbitmqctl join_cluster --ram rabbitrabbitmq-1
Clustering node rabbitrabbitmq-3 with rabbitrabbitmq-1 ...
[rootlocalhost ~]# rabbitmqctl start_app
Starting node rabbitrabbitmq-3 ...1默认rabbitmq启动后是磁盘节点在这个cluster命令下mq-2和mq-3是内存节点
mq-1是磁盘节点。
2如果要使mq-2、mq-3都是磁盘节点去掉--ram参数即可。
3如果想要更改节点类型可以使⽤命令rabbitmqctl change_cluster_node_type
disc(ram),前提是必须停掉rabbit应⽤
注:
#如果有需要使用磁盘节点加入集群[rootrabbitmq-2 ~]# rabbitmqctl join_cluster rabbitrabbitmq-1[rootrabbitmq-3 ~]# rabbitmqctl join_cluster rabbitrabbitmq-1登录上去有上面这几个即就是添加成功了
查看集群状态
# 在任意一个上面即可查看
在 RabbitMQ 集群任意节点上执行 rabbitmqctl cluster_status来查看是否集群配置成功。
在mq-1磁盘节点上面查看
[rootlocalhost ~]# rabbitmqctl cluster_status添加一个新的队列
添加队列 更改为集群可看 当前这个只有mq-1可用 修改 修改完之后就跟上面得一样了
[rootlocalhost ~]# rabbitmqctl set_policy ha-all ^ {ha-mode:all}RabbitMq负载均衡配置-HAProxy
安装HAProxy
[rootlocalhost ~]# yum install haproxy修改配置文件
[rootlocalhost ~]# vim /etc/haproxy/haproxy.cfg
